Don't act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good.
Marcus reminds us of urgency. Not to panic, but to wake up. Procrastination, he said, is the illusion of endless time. But life is a loan, not a guarantee. If you want to write, love, serve, build — do it now. He lived this daily, turning even quiet journal entries into immortal guidance.
Time is your most fragile asset. Spend it like it matters — because it does.
"Begin at once to live, and count each separate day as a separate life."
